my paypal ipn php works correctl. i tested it out with sandbox account, and the payment works, my database is updated properly etc.
however, I expected the page to redirect back to my shopping site. instead it just sits at paypal's Thank You For your Payment page.
how can i make it redirect back to my shopping site ?
In the payment form, you have to set a return field.
<input type="hidden" name="return" value="http://mywebsite.com/success.php" />
This will give the user a button that says: Go back to merchant's page. Additionally, if you want them to automatically be redirected back to your shopping site, without clicking anything, there's a profile option, in the PayPal website, called Auto Return.
Hope this helps :)
